Is Dexcom G6 Discontinued?
Dexcom G6 is discontinued — production stopped after 1 July 2026, and the resale market for it has since closed too. If you've switched to G7 you're probably holding sensors that won't work with it. Here's what changed, why the two systems don't mix, and what can actually be done with the leftovers.
Your G6 sensors won't work with a G7
The G7 has the transmitter built into each sensor, so there's nothing to pair a G6 sensor with. They don't work together in either direction. Whatever G6 stock you have when you switch stays unusable.
Dexcom stopped producing G6 sensors after 1 July 2026, which is why so many people are changing over at the same time rather than when their own supplies ran out.
Your old transmitter is left over too, and it isn't used up — it's reusable hardware with no expiration date on it. It is still G6 hardware though, and that market has closed: we no longer buy any G6, sensors, transmitters or receivers.
Dexcom G7 vs G6
The G7 isn't a revision of the G6, it's a different system — which is why nothing carries across when you switch. The differences that actually change day-to-day use:
| Feature | Dexcom G6 | Dexcom G7 |
|---|---|---|
| Transmitter | Separate reusable transmitter, replaced every 90 days | Built into every sensor — nothing separate to buy or swap |
| Warm-up time | 2 hours | 30 minutes |
| Wear time | 10 days | 10 days, plus a 12-hour grace period to change over |
| Size | Larger sensor with a separate transmitter clipped on top | All-in-one, and substantially smaller |
| Placement (adults) | Abdomen | Back of the upper arm |
| Accuracy (MARD, adults) | Around 9% | Around 8.2% |
| Fingerstick calibration | Not required | Not required |
| Cross-compatible | Needs G6 transmitter and receiver | Needs G7 hardware — the two systems don't mix |
These describe the systems as launched, for comparison — not as a substitute for Dexcom's own documentation. Check dexcom.com for current specifications, and your care team for anything to do with your own use.
Can I use my leftover G6 sensors with the G7?
No. The G7 combines the sensor and transmitter into a single unit, so there's no separate transmitter and no way to pair a G6 sensor with G7 hardware. They aren't cross-compatible in either direction. Any G6 sensors left when you switch stay unusable unless you go back to G6 hardware.
What happens to my old G6 transmitter?
Nothing useful, and unfortunately nothing saleable either. G6 transmitters last about 90 days and get moved between sensors; the G7 has no equivalent because the transmitter is inside each sensor. We no longer buy G6 hardware of any kind now that the resale market has closed — a sealed transmitter is a donation candidate rather than a sale.
Is Dexcom discontinuing the G6?
Dexcom stopped producing G6 sensors after 1 July 2026, so supply winds down from here. That's why so many people are switching at once rather than when their own supplies ran out — and why a lot of unused G6 stock is sitting in cupboards right now.
What actually changes when you switch?
The two differences people notice first are the built-in transmitter and the warm-up: G6 takes about two hours to warm up, G7 around 30 minutes. Beyond that, it's a different app and a different insertion. Your prescriber or diabetes educator is the right person to walk you through the rest — we're not the ones to advise on the switch itself.
Switching from Dexcom G6 to G7 with Omnipod 5 — does that work?
Omnipod 5 compatibility has been rolling out for G7, but which combinations work depends on your pod generation, your controller or phone, and the software version you're on. Check with Insulet and Dexcom for your specific setup rather than taking anyone's word for it, including ours. What we can tell you is that the changeover leaves people with G6 sensors they can't use.
What should I do with unused G6 sensors?
Don't bin them — but don't expect to sell them either. Now that G6 is discontinued the resale market has closed, and we no longer buy it in any form. Donation is the route that still works: sealed, in-date sensors are exactly what free clinics and charitable programmes can use, and there are people paying out of pocket who need what's sitting in your cupboard. It is worth ten minutes rather than the rubbish bin.
What to do with leftover G6 stock
We no longer buy Dexcom G6 — sensors, transmitters or receivers. Now that production has stopped, the resale channel for it has closed, so there is nowhere for us to place it and quoting on it would waste your time.
Don't bin it, though. Sealed, in-date G6 is exactly what free clinics and charitable programmes can still use, and someone paying out of pocket needs what is sitting in that cupboard. Where to donate medical supplies near you lists the Cleveland drop-offs and what each one takes.
Your G7 supplies are a different matter — here's what we pay for Dexcom G7 sensors, and how close to the expiration date they can still be sold. If you switched pumps at the same time we also buy Omnipod pods and Medtronic pump supplies. Not sure whether yours qualify? Here's what can and can't be sold.
